It means the Blackberry mobile is locked with a Australia network.So if you use the MEP(unlock) code you can remove the network lock and switch to any GSM network....To unlock approach unBBlock.com and remove the network lock permanently.Specify the mobile model,country,locked network and based on the availability you can get the unlock code along with free instructions.
